A series of more violent and powerful cases are appearing again in the Third season. Two investigators appear to be supernatural and strange to Willard Mill, and Dennis discovers a doll that can easily summon spirits. On the other hand, Stan, Evie and Kevin are trying to save Dennis after falling into a vampire disaster.

It was a very clever opening to Stan Against Evil Season 3 because it would have been impossible for Evie to guess she was getting punked by the version of Stan that returned from emptying his bladder.
